CROSSING-GATE.

SPECIFICATION forming part of Letters Patent No. 703,754, dated July 1, 1902.

Application filed March 10, 1902. Serial No. 97,469. (No model.)

gates for railway-crossings and the object is m to provide a gate withnovel and simple releasing and resetting devices arranged along the track and adapted to be operated by a locomotive passing along the track.

I will describe a crossing-gate embodying 15 my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specifiction, in which similar characters of reference indizo cate corresponding parts in allthe figures.

Figure 1 is a perspective view showing a gate embodying my invention. Fig. 2 is a detail showing one of the release-operating levers employed. Fig. 3 is a plan showing a 25 resetting-lever employed. Fig. 4 is a sectional View showing the locking mechanism, and Fig. 5 is a perspective View of a portion of the gate-bar.

The gate comprises a frame arranged at one side of a track, as here shown, andconsisting of uprights or posts 1 2, connected at the top by a cross-timber 3. The post 2 may be made in the form of two strips, and arranged between these strips is the gate-bar 4, the pivotal connection of said gate-bar being near the lower end of the post 2. Rearward of its pivotal point the gate is weighted, as at 5, so that when released it will be automatically swung upward to the position indicated in full lines in Fig. 1. From the gate, rearward of its pivot, a rod or wire 6 extends to a connection with one member of an anglelever 7, pivoted in standards on the crosstimber 3, and from the other or verticallydisposed member of this angle-lever a link 8 extends to a connection with the upper end of a lever 9, mounted in standards 10 on said cross-timber, and from the opposite side of the upper end of this lever 9 aspring 11 extends to a fixed post or standard 12 on the cross-timber. This spring 11 is designed to swing the gate to its closing position, as will be hereinafter described.

The lowerendof the lever 9 is connected by means of a link or red 13 with the up wardly-disposed member of an angle-lever 14, mounted in a standard on the cross-timber 3, and from the other member of this angle-lever 14 a draw-rod 15 extends downward to connection with the horizontally-disposed member of an angle-lever 16, pivoted in a standard 17 arranged at thebase of the post 1.

Arranged at one side of the track or between the track and the gate and in line with the angle-lever 16 is a guide-frame 18 for a locking-block 19. This locking-block 19 has a stem 20, extended loosely through the top member of the frame 18, and arranged between this said top member and the block is a spring 21, which tends to force the block downward to its locking position with a sliding bar 22, mounted to slide transversely through the frame 18 and having bearings in standards 23. This bar 22 is provided with a notch, as clearly shown in Fig. l, to receive the end of the block 19. A spring 24 connects one end of the sliding bar 22 with the downwardly-disposed member of the angle-lever 16.

Pivoted to one side of the frame 18 is an angle-lever 25, which at its upper endhas piv+ .otal connection with the block 19, and from its lower end a draw-rod 26 extends to a connection with a rock-shaft 27, arranged at one side of the track, and connected to the inner end of this rock-shaft 27 is a lever 28, designed to be engaged by a part carried by a trainsuch, for instance, as a Wheel or tappet-arm attached to a locomotive. At the 0pposite side of the frame 18'is a pivoted lever 29, the upper end of which is connected to the block 19, while from the lower end a drawrod 30 extends to connection with one member of a horizontally-swinging angle-lever 31, and from the other member of this angle-1ever a rod 32 extends across the track and inner rails to connection with one member of a horizontally swinging angle-lever 33, the other arm of the angle-lever 33 havinga draw- This spring will relieve the parts from undue shock when operated by a train.

rod connection 34 with a rock-shaft 35, on the inner end of which is a lever 36, designed to be forced downward by the part carried by the locomotive, as described in connection with the lever 28. It will be seen that the levers 28 and 36 are arranged at opposite sides of a track, so that it will be necessary for an operating device to be placed on one side only of a locomotive, and these levers, it is to be understood, are to be placed a sufficient distance from the gate to operate the same before the locomotive reaches the gate.

llrom the inner end of the bar 22 a link 37 extends underneath a rail of the track and is attached to the forward end of a longiturear portion of the gate-bar 4 will move the said gate down to its closing position, as indicated in dotted lines in Fig. 1. Of course during the sliding movement of the bar 22 to release the tension of the spring 11 theresetting-lever 38 will be drawn toward the rail, so that when the locomotive reaches the crossing the flange of its forward wheel will engage against said resetting-lever, swinging it inward or toward the center of the track, and consequently drawing the bar 22 to its lookingposition to be engaged by the block 19. This movement will again reset the spring 11 and the weight 5 will cause the gate to swing to open position.

As indicated in Fig. 5,the gate,near its pivotal point,is provided with a double-hinge 39, which will permit the gate to be swung laterallyin either direction. This will be found of service should a person driving a team be caught between the gate and the track, or it may be swung inward from the opposite side to permit an attendant to pass through while the train is approaching.

While I have shown the gate as arranged at one side ofthe track, it is to be understood that a gate may be arranged at each side.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A crossing-gate comprising a frame, a gate-bar mounted to swing in said frame, a spring for moving said gate-bar to closing position, a sliding bar arranged atone side of the track and operating to release the spring tension, a locking device for said bar, and devices actuated by a train for moving the looking device out of engagement with the sliding bar, substantially as specified.

2. A crossing-gate comprising a frame, a gate-bar mounted to swing in the frame, a

spring for moving said gate-bar to closing po- 4 sition, a sliding bar arranged at one side of the track and having connections for releasing the tension of the'spring, a locking-block for.

, guided vertically in said frame, angle-levers mounted on opposite sides of the frame and having pivotal connection with the block, rock-shafts arranged at opposite sides of the track and at opposite sides of the crossing,

connections between said rock-shafts and the angle-levers,and levers mounted on said rookshafts and adapted to be engaged by a part carried by a train, substantially as specified.

4:.
